- Emissions from gas and oil used
in the production of steel have increased dramatically
since the 1950's and have contributed significantly
to acid rain- sterilizing our lakes and rivers -
killing our trees and wildlife.
- Aluminum production results in 8 times
the air emissions and 300 times the water consumption
as lumber production.
- Concrete production is estimated to
emit almost 3 times more carbon dioxide,
carbon monoxide and hydrocarbons, and produces
5 times more solid waste than the production
of lumber.

In contrast, wood does what wood substitutes cannot do.
While trees grow, they absorb carbon dioxide, cleaning
the air we breathe. |
